A lot of people won't agree with me here, but this item has been somewhat distorted and sensationalised by the news.
What it should have read as is "Woman fined for driving 7 miles to a beauty spot".
Her job is irrelevant. If she'd stopped at a location on her way home that would have been different, but she drove 7 miles in the opposite direction to her home after the appointment.
It's also irrelevant that she was having lunch.
There's a separate debate about whether or not we should be fining people for travelling to these beauty spots, but I guess if they didn't, lots of people would be going there, they'd be crowded and then you do have a problem.
But this is the police doing their job as they've been told to - no more, no less.
